In English, the predominance of stressed syllables as word onsets aids lexical segmentation in degraded listening conditions. Yet it is unlikely that these findings would readily transfer to languages with differing rhythmic structure. In the current study, the authors seek to examine whether listeners exploit both common word size (syllable number) and stress cues to aid lexical segmentation in Spanish. Forty-seven Spanish-speaking listeners transcribed two-word Spanish phrases in noise. As predicted by the statistical probabilities of Spanish, error analysis revealed that listeners preferred two- and three-syllable words with penultimate stress in their attempts to parse the degraded speech signal. These findings provide insight into the importance of stress in tandem with word size in the segmentation of Spanish words and suggest testable hypotheses for cross-linguistic studies that examine the effects of degraded acoustic cues on lexical segmentation.
在英语中，重读音节作为单词起始部分的优势有助于在听力条件不佳的情况下进行词汇切分。然而，这些研究结果不太可能轻易适用于具有不同节奏结构的语言。在当前的研究中，作者试图检验听众是否利用常见的单词长度（音节数量）和重音线索来辅助西班牙语中的词汇切分。47名讲西班牙语的听众转录了有噪声干扰的双词西班牙语短语。正如西班牙语的统计概率所预测的那样，错误分析表明，听众在试图解析 degraded speech signal 时，更喜欢带有倒数第二个音节重读的双音节和三音节单词。这些发现深入了解了重音与单词长度在西班牙语单词切分中的重要性，并为跨语言研究提出了可检验的假设，这些研究考察了 degraded acoustic cues 对词汇切分的影响。
